HARROW.

SPEGIFCATION forn'ing` part of Letters Patent No. 738,361, datedSeptember 8, 1903.

Application filed February 9 To @ZZ whom t may concern.'

4Be it known thatI, GEORGE D. SoHLossER, a citizen of the United States,residing at Sunnyside, in the county of Yakima and State of Washington,have invented certain new and useful Improvements in I-Iarrows; and I dodeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention is an improved harrow; and it consists in the peculiarconstruction and combination 0f devices hereinafter fully described andclaimed.

The object of my invention is to provide a flexible beamless barrow theteeth of which are movable verticallyindependently of each other toadapt the barrow to conform to inequalities in the surface of the soil,and hence increase the efficiency of the harrow.

One object 0f my invention is to effect improvements in the constructionof the harrow-teeth.

Another object is to combine a plurality of the harrowteeth with linkdevices which flexibly connect them together.

In the accompanying drawings, Figure l is a top plan View showing aportion of a harrow constructed in accordance with my invention. Fig. 2is an elevation of the same. Fig. 3 is a view similar to Fig. 1, showinga modified construction of the harrow. Figs. et and 5 are detail viewsshowing modified constructions of the links which connect thebarrow-teeth together, and Fig. 6 is a similar view showing a modiliedform of harrowtooth.

In the preferred form of my invention (shown in Fig. l) each ofthebarrow-teeth 1 is polygonal in crosssection, has concaved sides 2 formedwith sharpened cutting edges 3 at the angles, and the ends of the toothare pointed, as at 4, so that either end of the tooth may be used.Midway, or substantially so, between the ends of each harrowtooth thesame is provided with radially-projecting ears 5, which are formedintegral with the tooth, and the said ears are provided with transverseopenings 6, adapted for the reception of link devices 7, which areemployed to connect the teeth together in series and in such manner thateach harrow-tooth 1903. Serial No. 142,504. (No model.)

is movable vertically independently of the others. The barrow-teeth andthe link devices 7, which connect them dexibly together, constitute aflexible barrow fabric which is adapted to conform perfectly toinequalities in the soil when the barrow is in operation, so that thedepressed portions, ruts, and the like in afieldwill be harrowedeffectually, as well as the more elevated portions of the field. Thefront row of barrow-teeth may, as here shown, be flexibly connected to adraw-bar ct by means of hooks or similar devices l); but any approvedmeans may be employed for drawing the harrow across` a field, and I donot limit myself in this particular.

In the form of my invention shown in Fig. 3 the barrow-teeth lm aretriangular in crosssection andthe sides 8 thereof are flat. Eachbarrow-tooth has at its front edge at a point` intermediate its ends anopening 9 and is provided on its rear side with a rearwardlyprojectinglug 10, having an opening l1. The link devices employed in this form ofmy invention are rods 12, of suitable length, which are passed throughthe openings 11 and are provided with rearwardly-extending offsetportions 13, which engage the openings 9. It will be observed byreference to Fig. 3 that the barrow-teeth l are disposed in rows onebehind another and that the barrow-teeth are set alternately, so thateach barrow-tooth is directly opposite and in front of the space betweentwo barrow-teeth behindiit.

By connecting the link devices to the intermediate portions of thebarrow-teeth and pointing both ends of the latter, as herein described,the barrow-teeth may be used with either side down, so that itsefliciency is very greatly prolonged. It will be further understood thatin the event that a barrow-tooth or link device becomes broken the samecan be readily replaced at very small cost. fIdo not desire to limitmyself tol the precise construction and combination of devices hereinshown and described, as it is evident that modifications may be madetherein without departing from the spirit of my invention and within thescope of the appended claims.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, ism

l. A harrow comprising a plurality of teethr each having openingsbetween its ends, and links flexibly engaged with said openings and eachconnecting a plurality of the teeth together, substantially asdescribed.

2. A harrow comprising a plurality of teeth each provided on its frontand rear sides with openings between its ends, and links engaged withsaid openings and each connecting a plurality of the teeth together, theaxes of the teeth being substantially central with relation to thelinks, substantially as described.

3. A harrow comprising teeth each provided on its front and rear sideswith openings between its ends, and arranged in rows, the teeth of therespective rows being opposite the spaces between the teeth of theadjacent rows, and link-rods extending transversely GEORGE D. SOHLOSSER.Witnesses:
